Windows Nt 4.0 Server; Configuring A Machine To Run Directory Server - Netscape DIRECTORY SERVER 6.0 Installation Manual

The
tcp_time_wait_interval
that a TCP connection will be held in the kernel's table after it has been closed. If its
value is above 30000 (30 seconds) and the directory is being used in a LAN, MAN
or under a single network administration, it should be reduced by adding a line
similar to the following to the
/etc/init.d/inetinit
ndd -set /dev/tcp tcp_close_wait_interval 30000
The
tcp_conn_req_max_q0
maximum backlog of connections that the kernel will accept on behalf of the
Directory Server process. If the directory is expected to be used by a large number
of client hosts simultaneously, these values should be raised to at least 1024 by
adding a line similar to the following to the
ndd -set /dev/tcp tcp_conn_req_max_q0 1024
ndd -set /dev/tcp tcp_conn_req_max_q 1024
The
tcp_keepalive_interval
packets sent by Solaris for each open TCP connection. This can be used to remove
connections to clients that have become disconnected from the network.
The
tcp_rexmit_interval_initial
server performance testing on a LAN or high speed MAN or WAN. For operations
on the wide area Internet, its value need not be changed.
The
tcp_smallest_anon_port
that can be made to the server. When
4096, this value should be decreased, by adding a line similar to the following to
the
/etc/init.d/inetinit
ndd -set /dev/tcp tcp_smallest_anon_port 8192
The
tcp_slow_start_initial
predominately be using the Windows TCP/IP stack.

Windows NT 4.0 Server

This section describes how to install Directory Server on Windows NT.

Configuring a Machine to Run Directory Server

Directory Server should be installed on a computer which is isolated from the
public Internet by a network-level firewall. This is necessary to protect the NT
operating system from IP-based attacks.
